But how would this compete with a shader that is done in one pass? You're right about the borders. They are ugly when doing zooming in the way I described. Thanks for the input.

Suppose you want to render 64 passes of zoom blur, only 6 passes are needed. First make a blended images between zoom factor 0 and 32 and render this to a texture. Then use this as the source of your next pass. In the next pass you render your image with a blend between zoom factor 0 and 16. The result of this second pass contains zoom factor 0, 16, 32 and 48. ect. This gives you a nice number of zoom factors in small number of passes. And, instead of zooming out, I would zoom in, that saves you from the annoying borders at the sides. Good luck, Ilja There is a better way to do a zoom blur filter.
